Scalin: Weight Tracker

A little buddy for the ups and downs.

Scalin is a weight tracker with a small companion and a big personality. Log your weigh-ins, follow a smoother trend, and get a little perspective when today's number surprises you.

YOUR TREND, WITH CONTEXT
See how your weight is changing over time. Scalin smooths your weigh-ins into a trend estimate, called "true weight" in the app, so you can look beyond a single reading. Track your weekly pace, set a goal, and explore an estimated range for a future date as your history builds.

A COMPANION WITH CHARACTER
Your little buddy follows you around the app and comments on your progress, pauses, and daily ups and downs. Choose Supportive, Snarky, or Merciless to find your kind of company. Change the tone whenever you like, or mute a line that doesn't land.

MAKE ROOM FOR THE WHOLE JOURNEY
Track weight loss, gain, or maintenance in kg or lb. Review your history, add a missed weigh-in, and edit an entry when you need to. Record notes and possible reasons for a change, then look back at the bigger picture. Celebrate milestones along the way.

ON A WEEKLY GLP-1?
Turn on shot tracking during setup or in Settings. Today marks your shot day, your chart marks each shot, and after a few weeks Scalin shows which days after a shot your weigh-ins run lowest and highest against your trend. Log the dose, the injection site (Scalin suggests the next one) and how the days after felt. Add an optional shot-day reminder. Scalin keeps the record; decisions about your medication stay with your clinician.

FITS INTO YOUR MORNING
- Log on iPhone, or use the Digital Crown on Apple Watch.
- Connect Apple Health to import weight history and save new weigh-ins, with your permission.
- Bring in readings from a smart scale through Apple Health if its app saves weight there.
- See your trend in widgets, Apple Watch complications and, if you like, the Dynamic Island.
- Ask Siri about your trend, or ask Scalin directly, answered on your iPhone.
- Set an optional weigh-in reminder.

KEEP YOUR NUMBER PERSONAL
Widgets keep your absolute weight hidden by default. Add an app lock with Face ID, Touch ID, or your device passcode, and export your history as CSV whenever you need it. No Scalin account is required.

Scalin focuses on weight tracking. It doesn't count calories, calculate BMI, prescribe a diet, or advise on medication. Trends and forecasts are estimates based on your entries, not medical measurements or guarantees of future results.

SUBSCRIPTION
A subscription is required to use Scalin after setup. Available plans, prices, and any free trial you are eligible for are shown before purchase.

Payment is charged to your Apple Account when you confirm a purchase, or at the end of an applicable free trial. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel your subscription in your Apple Account settings.
